The woman died two weeks after receiving her first AstraZeneca shot. At the time the health ministry confirmed that her death was was due to "a cerebral haemorrhage associated with thrombocytopenia and disseminated intravascular coagulation."
The attending physician did not rule out a link between the death and the vaccine received two weeks earlier and the prosecutor in April ordered an autopsy.
A review of the woman’s medical file and the autopsy concluded that the thrombocytopenia was caused by the vaccine against covid-19. The National health laboratory (LNS) and Greifswald Medical School, a division of the University of Greifswald in Germany, carried out the expert assessment.
The Luxembourg public prosecutor has closed the case without criminal proceedings, as no criminal offence could be established, it said. The health directorate was informed of the results of the investigation and was also given a copy of the expert reports.
AstraZeneca’s vaccine, also known as Vaxzevria, has been authorised by the European Medicines Agency (EMA), which considers that its benefits are greater than its risks. Thrombosis in combination with thrombocytopenia may affect up to 1 in 10,000 people, it says on its website.
